Abstract

Un arbre rotatif de sortie d'un moteur à combustion interne porte un élément rotatif pour générer des signaux correspondant à des groupes prédéterminés de cylindres et des signaux pour identifier un groupe particulier de cylindres, et le groupe particulier de cylindres est identifié sur la base de ces signaux. Au moment du démarrage du moteur à explosion, lors d'une coupure du carburant ou d'un fonctionnement à vitesse régulière et constante, la quantité de carburant injectée à un cylindre particulier dans un groupe particulier de cylindres est rendue différente de celle des autres cylindres dans ce groupe particulier de cylindres, au moment de l'injection dans ce groupe. Les résultats de l'identification permettent de référencer ce cylindre particulier dans le groupe de cylindres. La fluctuation en rotation et le résultat de l'identification des groupes de cylindres, à cet instant, sont utilisés pour évaluer la véracité des suppositions ci-dessus et l'évaluation des cycles et des phases des cylindres respectifs est utilisée pour identifier un cylindre. A cet instant, une commande de régulation de la fréquence de rotation est réalisée par rapport aux autres cylindres.
